1. Hordhac
Polyethylene terephthalate (PET) waa mid ka mid ah heerkulbeegyada ugu isticmaalka badan uguna isticmaalka badan adduunka. Maaddaama ay tahay walxaha aasaasiga ah ee dhalooyinka cabitaanka, baakadaha cuntada, iyo fiilooyinka synthetic, PET waxay isku daraysaa sifooyin jireed oo aad u wanaagsan iyo dib-u-warshadeyn. Maqaalkani waxa uu eegayaa sifooyinka muhiimka ah ee PET, hababka habaynta, iyo codsiyada kala duwan ee warshadaha.
2. Qalabka Agabka

- Iska caabbinta kulaylka: Adeegsan kara ilaa 70°C (150°F) oo joogto ah
- Cufnaanta: 1.38-1.40 g/cm³ (amorphous), 1.43 g/cm³ (crystalline)
Iska caabinta Kiimikada
- Iska caabin heer sare ah oo biyaha, khamriga, saliidda
- Iska caabin dhexdhexaad ah asiidhyada/saldhigga daciifka ah
- Iska caabbinta liidata ee alkalis xooggan, dareerayaasha qaarkood
Xogta Deegaanka
- Xeerka dib u warshadaynta: #1
- Khatarta Hydrolysis: Waxay hoos u dhigtaa heerkulka sare/pH
- Dib-u-warshadaynta: Waxaa dib loo habayn karaa 7-10 jeer iyada oo aan khasaare weyn oo hanti ah la helin
3. Hababka Habaynta
| Habka | Codsiyada caadiga ah | Tixgelinta Muhiimka ah |
|---|---|---|
| Isku-dubarid Fidista afuufidda | Dhalooyinka cabitaanka | Jihaynta Biaxial waxay hagaajinaysaa xoogga |
| Soo saarid | Filimada, go'yaal | Waxay u baahan tahay qaboojin degdeg ah si loo caddeeyo |
| Fiber Spinning | Dharka (Polyster) | Xawaaraha sare ee wareegga 280-300 ° C |
| Thermoforming | Saxarada cuntada | Kahor qalajinta lagama maarmaanka ah (≤50 ppm qoyaan) |
4. Codsiyada waaweyn
Baakadaha (73% baahida caalamiga ah)
- Dhalooyinka cabitaanka: 500 bilyan oo unug sannadkii
- Weelasha cuntada: saxaarad mikrowavable ah, qolof salad ah
- Daawooyinka: Xirmooyinka finanka, dhalooyinka daawada
Dharka (22% baahida)
- Polyester Fiber: Dharka, dharka
- Dharka Farsamada ah: Suunka fadhiga, suumanka qaada
- Nonwovens: Geotextiles, warbaahinta sifaynta
Isticmaalka soo baxaya (5% laakiin sii kordhaya)
- Daabacaadda 3D: Filadaha xoogga badan
- Elektrooniga: filimada dahaarka, qaybaha capacitor
- Tamarta la cusboonaysiin karo: xaashida dambe ee laysarka qoraxda
5. Horumarka Joogtada ah
Tignoolajiyada dib-u-warshadaynta
- Dib-u-warshadaynta makaanikada (90% PET dib loo warshadeeyay)
- Habka dhalaalinta-dhar-flake
- Heerka-cuntadu waxay u baahan tahay nadiifin sare
- Dib u warshadaynta Kiimikada
- Glycolysis/depolymerization ilaa monomers
- Nidaamyada enzymatic ee soo baxaya
Bio-based PET
- 30% dhirta ka soo jeeda qaybaha MEG
- Farsamada Coca-Cola's PlantBottle™
- Qiimaha hadda jira: 20-25%
6. Isbarbardhigga balaastikada Alternative
| Hanti | PET | HDPE | PP | PLA |
|---|---|---|---|---|
| Caddayn | Aad u fiican | Madmadow | Translucent | Wacan |
| Heer kulka Isticmaalka ugu badan | 70°C | 80°C | 100°C | 55°C |
| Ogsajiinta xannibaadda | Wacan | Miskiin | Dhexdhexaad | Miskiin |
| Heerka dib u warshadaynta | 57% | 30% | 15% | <5% |
7. Muuqaalka Mustaqbalka
PET waxay sii wadaa inay maamusho baakadaha hal-isticmaalka ah iyadoo ku fidinaysa codsiyada waara iyada oo loo marayo:
- Tiknoolajiyada xannibaadaha ee la xoojiyey (SiO₂ daahan, lakabyo badan)
- Kaabayaasha dib-u-warshadaynta horumarsan (PET kiimikaad dib loo warshadeeyay)
- Wax ka beddelka waxqabadka (nano-composites, saamaynta wax ka beddelayaasha)
Iyada oo dheellitirkeeda gaarka ah ee waxqabadka, hab-socodka iyo dib-u-warshadaynta, PET ayaa weli ah mid aan looga maarmin dhaqaalaha balaastikada adduunka iyada oo loo gudbayo qaababka wax-soo-saarka wareegtada ah.
